Abstract Quantile regression is a popular tool for modelling the conditional quantiles of a response as a function of one (or more) independent variables. Quantile curves for different probabilities often cross. In theory this is not possible, but it is frequently encountered in small data sets. We propose to estimate all quantile curves simultaneously with a surface, a so-called quantile sheet. This sheet is fitted with a sum of tensor products of B-splines with two penalties to control for smoothness.
